Hello,
My headphone worked before, however, after some installation and update, I found there was no sound on my T61 any more. I have tried "alsamixer -c0" or "gst-mixer" to unmute all "MM" stuff, however it did not work. At present, the only thing I can hear is the electronic noisy in my headphone. Could anybody help me? Any comment will be really appreciated!!
Thanks in advance.

Are there physical mute and volume buttons on your laptop? I have pressed the mute button on occasion, which appeared to break the sound. Pressing the volume-up button brings it back.
yeah, thanks for your input, but I believe I have tried that, not mute physically. Still no sound.

In fact, on my T61, the mute button is non-functional. I've discovered that turning the volume all the way down turns on the mute indicator in GNOME, but it would be nice if the mute button actually toggled mute the way it's designed to.
I'd like to file this as a bug, but I'm not sure what component to file it against. Suggestions welcome.
TIA.

I boot into live CD fedora 11 again, and it turns out both my headphone and speaker work well(actually even the mute button is ok). but there is still no sound when booting into my HDD F11.
And I find something is different between those two os. Run "alsamixer -c0" in HDD F11, I see configuration options like: Master Headphon Speaker PCM Mic Mic Boos S/PDIF S/PDIF D ... Internal
while in live CD F11, I could see configuration options like: Master Headphon PCM Mic Mic Boos IEC958 IEC958 D IEC958 P ... Speaker
The configuration options' sequence is different( for example *Speak*) , IEC958 disappear and S/PDIF is new.
Has it to do with "no sound" issue? For example some inappropriate update?

Interesting - my T61 has a functioning mute button.
I think you need to update your BIOS. I got this from the Lenovo ChangLog for the T61 BIOS.
- (Fix) (ThinkPad T61/T61p only) Volume and mute buttons on the keyboard do not work on Linux.
That was in version 1.26-1.06. They're much beyond that now.

Ooh, that's a great idea. I updated, but it didn't help.
Forgot to check the version, but dmidecode now reports BIOS 2.38 and Firmware 1.8.
Thanks for the suggestion, though.
